VENTILATOR.

Application le April 2l, 1924.

To @ZZ who/m t may concern.'

Be it known that I, JosnrH II. FATTA, a citizen of the United States, residing at Honolulu, in the county of Honolulu and Territory of I-Iawaii, have invented certain new and useful Improvements in a Ventila tor, of which the following is a specilication.

This invention relates to new and useful improvements in ventilators which are principally adapted for use in connection with the port holes provided in the staterooms of a ship.

One of the important objects of the present invention is to provide an automatic means for closing the port hole when the waves or water strike a portion of my ventilator thereby preventing any possibility of the water from entering the staterooms through the port holes, means being further provided for automatically returning the ventilator to its normal position whereby the port hole is again opened so as to admit air therethrough.

A further object of the invention is to provide a ventilator of the above mentioned character, which may be easily and conveniently placed in position in the port holes of a ship without materially altering the construction of the ship, the ventilator being at all times posit-ive in its operation.

A further object of the invention is to provide aventilator of the above men` tioned character, which is, simple in construction, ineXpensive, strong and durable and furthermore adapted for the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming a part of the specification, and in which like numerals designate like parts throughout the same,

Figure l is a front elevation of my improved ventilator showing the same in position,

Figure 2 is a longitudinal section therethrough, and

Figure 8 is a transverse section taken approximately on line 3-3 of Figure l.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral l designates generally my ventilator which Serial No. 707,929.

comprises the elongated casing 2, the same being substantially cylindrical', the forward portion of the casing i-s cut away for its greater length as more clearly shown` in Figure 2 of the drawing to provide a substantially semi-circular outwardly projecting portion The inner end or base portion 4 of the casing is adapted to lit snugly in the port hole A of a vessel B in the manner clearly shown so that the forward end of the casing will extend beyond the outer face of the side of the vessel. For permitting the ventilator to be placed in position in the port hole A and to further prevent the displacement therefrom, I provide the handle the ends of which are secured to the inner end of the casing and are flared outwardly as shown at o in the drawing to engage the inner side of the vessel adjacent the port hole.

Extending forwardly from the semicircular portion 3 of the casing 2 are the an,- gular brackets 7, the forward ends of which are bent downwardly as shown at S to provide stops, the brackets 7 forming a guide means for the elongated plate 9 which is curved transversely. rlhe plate 9 is adapted to be supported between the brackets 7 in the manner clearly illustrated in the drawing and for the purpose of normally holding the same in a forward position, I provide the coil springs l0, the rear portions of which are supported in suitable brackets ll mounted on the inner face of the semicircular portion 3 of the casing. The bent portions 8 provided on the forward ends of the brackets 7 provide a means for limiting the forward movement of the plate 9 and the plate 9 is adapted for lateral movement on the brackets 7 for the purpose to be hereinafter more fully described. Suitable bracing means such as is shown at l2 is adapted to extend acrosss the bent down portions 8 of the brackets 7 and secured thereto in any well known manner and the ends of braces l2 are secured to the top and bottom of the semi-circular portion 3 of the casing 2 and provide a means for rigidly supporting the forward ends of the brackets 7 in the manner clearly illustrated.

Extending transversely through the central portion of the inner end of the casing 2 is the rod 13 and pivotally supported thereon is the closure pla-te or damper lil. The damper is adapted to conform to the contour of the inner portion of the casing and in the present invention is shown as being circular to conform to the cylindrical conformation of the base portion 4 of the casing. The closure or damper 14 is adapted to cooperate with the spaced baffle flanges 15 and 16 respectively which are arranged on the inner end of the casing in the vmanner shown in Figure 1 of the drawing so that the outer edges of the closure will engage the anges when in a closed position in the manner as will be presently described.

Pivotally connected to the damper 14 is the link 17 the latterbeing pivotally connected to the closure or damper by means of the bracket 18 and this link is twisted intermediate lits ends as shown more clearly in the drawing and the opposite end of the link `is connected to the outer end of the longer arm of the bell crank lever 19. The bell crank lever 19 is pivoted at 20 in the bracket 21 supported by the rear wall of the casing and the outer end of the shorter arm of the bell crank lever is pivotally connected to the inner end of the plate 9 as shown at 22 in the drawing. The connection of the character above described provides a means whereby the damper will operate simultaneously wlth the operation of the plate 9.

Normally'the parts are arranged as shown in the drawing wherein the springs 10 normally keep the plate 9 in a forward position and the damper 14 is in an open position and out of engagement with the` fianges 15 and 16 Y' so that air may circulate around the inner walls of the casing and will pass through the inner end of the same into the port hole and stateroom.

It is of course to be understood that the forward portion or open part of the casing is disposed in the same direction in which the Ship is traveling so as to cause the air cur-l rents to be deflected by the outwardly projecting portion of the casing and be directed into the state room in the port hole of which is mounted the ventilator. To prevent water or the waves from entering the stateroom through the port hole and through the ventilator, 1t will be readily seen that when the waves strike the plate 9 the same will move rearward against the tension of the springs 10 simultaneously swinging' 'the damper 14 on its pivot 13 through the connection of the bell crank lever and the link above described so that the damper will engage the flanges 15 and 16 and will be closed thus preventing the possibility of any water from entering through the port hole and into the stateroom.y After the water or waves have recede'd, the springs 10 will return the plate 9 and the damper 14 connected thereto to their normal positions whereby air will again be admitted to the stateroom. For the purpose of permitting water which may accumulate in the base portion of the casing to be discharged, I provide the opening 23.

It will thus be seen from the foregoing description, that a ventilator for use in connection with the port hole of a vessel has been provided which will automatically close the port hole when the waves or water come in contact therewith and will automatically reopen the port hole when the waves have receded. The simplicity with which my device is constructed enables the same to be easily and readily placed in position-on a vessel and will at all times be supported in an operative position. A device of this character mayr be turned depending upon the direction in which the ship travels so that the front or forward face of the casing which is cut away will be disposed inthe direction of travel which the ship pursues. A device of the character described may be further manufactured at a very low costr and will be strong and durable.

While I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, sha-pe and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended..
